临界正畸患者不同处理措施对牙硬组织变化的研究

The Influence of Different Treatments on Dental Hard Tissue in Critical Orthodontic Patients

目的:探讨临界正畸患者不同处理措施对牙硬组织的影响,旨在提高患者的生活质量,采取最佳的治疗措施。方法:将2008年1月-2009年6月在我院牙科进行诊治的临界正畸患者28例,根据不同的处理措施分为两组,拔牙组与非拔牙组。随访并比较两种处理措施的临床疗效。结果:两组在牙齿排列、覆颌覆盖、中线、侧方咬合及总分间的差异均无统计学意义(p>0.05);而拔牙组的侧貌远高于对照组,且差异具有统计学意义(p<0.05)。拔牙组与未拔牙组在患者满意度间的差异无统计学意义(p>0.05)。结论:对临界正畸患者采取不同的处理措施对牙硬组织具有不同的疗效,在实际临床工作中,应根据实际情况采取不同的治疗措施。

Objective： To investigate the influence of different treatments on dental hard tissue in critical orthodontic patients, aimed at improving the quality of patients＇ life and take the best treatment. Methods： 28 critical orthodontic patients were treated in our hospital from January 2008 to June 2009.All patients were divided into two groups, extraction group and the non-extraction group, according to the different treatment measures. Follow-up and compare the clinical efficacy of two treatments. Results： The teeth arrangement, covered jaw coverage, midline, lateral and total occlusion showed no significant difference between two groups （p〉 0.05）; the profile of extraction group is higher, and the difference was statistically significant （p 〈0.05）. The patients＇ satisfaction in two groups have no significant difference （p〉 0.05）. Conclusion： There are different efficacy of treatment measures to dental hard tissues. In clinical work, different therapeutic measures should be taken based on the actual situation.
